Prayer is the vital breath of religion in the soul. It cultivates our sense of dependence and of God’s sovereignty. By confessing our sins, the sense of sin is deepened. By rendering thanks, gratitude is enlivened. By adoring the divine perfections, we are changed into the same image, from glory to glory. From all this it is apparent that prayer is the Christian’s vital breath. If God had not required it, the Christian would be compelled to offer it by his own irrepressible promptings. If he were taught to believe that it was not only useless, but wrong, he would doubtless offer it in his heart in spite of himself, even though he were obliged to accompany it with a petition that God would forgive the offering. To have no prayer is, for man, to have no religion.
